Title: Silicon-polymer dielectric film on semiconductor substrate and method for forming the film
Inventor: MATSUKI NOBUO
IPC: C23C14/00
Filed: 2001-10-18
Abstract: PROBLEM TO BE SOLVED: To provide a method and materials for forming a dielectric film having a low dielectric-constant, high heat-resistance, superior adsorption-proof, and good adhesion. SOLUTION: The method for forming a silicon-polymer dielectric film having a low dielectric-constant, high heat-resistance, and superior adsorption-proof, is applied to a plasma CVD apparatus. The first process is to vaporize a silicon- based hydrocarbon compound which is expressed by, general formula α0βCxHy (α=3, β=3 or 4, x and y integers), and then introduce the vaporized compound into the reaction chamber of the plasma CVD apparatus. The next process is to introduce an additional gas into the reaction chamber. The residence time of the material gas can be elongated by reducing a sum of flow of the reaction gas using a method for forming a silicon-compound film having continuously-porous structure with low dielectric-constant.

Title: Clipper
Inventor: SHIMADA HIROMI
IPC: F16B37/02
Filed: 2001-10-02
Abstract: PROBLEM TO BE SOLVED: To shorten an operation period of time and reduce cost by changing a bolt and nut used for a support fitting in piping work or the like, from the screw type to the clip type. SOLUTION: A bolt and nut used for a support fitting is used to prevent the fitting from dropping. Accordingly, as is conventionally done, the bolt and nut does not always have to be the screw type since load is not axially applied, although load is applied to the bolt itself. In addition, in the case of using a nut, there is a risk that the nut comes off by vibration or other factors if fastening the nut is forgotten or once the fastened nut comes loose. In the case of a clipper, since the clipper bites into a bolt, no loosening occurs. Accordingly, it improves working efficiency easily if a tool for clipping is used according to usage.
